So, while that also has been a common failure mode that we've been seeing with barrier usages, what you're suggesting isn't the right balance either. It's error-prone in a different way as amply exemplified in this very thread. It ended up making what should have been a straight-forward writer-reader interlocking into a maze in which one can easily be lost. I think you should be able to see that after this thread. Both misusages can be solved by understanding and sticking to established patterns and making exceptions only when explicitly justifiable and with ample explanation.
